ACCA (St), bishop of Hagustaldt, or Hexham, in Northumberland, succeeded Wilfrid in that see in 709. He ornamented his cathedral in a most magnificent manner: he furnished it also with plate and holy vestments; and erected a noble library, consisting chiefly of ecclesiastical learning, and a large collection of the lives of the saints, which he was at great pains to procure.—He was accounted a very able divine, and was famous for his skill in church-music. He wrote several pieces: particularly, Passiones Sanctorum, the Sufferings of the Saints: Pro illustrandis scripturis, ad Bedam; For explaining the scriptures, addressed to Bede. He died in 740, having enjoyed the see of Hexham 31 years, under Egbert king of the Northumbrians.
